Enabling the Plugin#

The example below enables the ext-plugin-pre-req Plugin on a specific Route:

curl -i http://127.0.0.1:9180/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/index.html",
"plugins": {
"ext-plugin-pre-req": {
"conf" : [
{"name": "ext-plugin-A", "value": "{\"enable\":\"feature\"}"}
]
},
"upstream": {
"type": "roundrobin",
"nodes": {
"127.0.0.1:1980": 1
}
}
}'

Example usage#

Once you have configured the External Plugin as shown above, you can make a request to execute the Plugin:

curl -i http://127.0.0.1:9080/index.html

This will reach the configured Plugin Runner and the ext-plugin-A will be executed.

Disable Plugin#

To disable the ext-plugin-pre-req Plugin, you can delete the corresponding JSON configuration from the Plugin configuration. APISIX will automatically reload and you do not have to restart for this to take effect.

curl http://127.0.0.1:9180/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/index.html",
"upstream": {
"type": "roundrobin",
"nodes": {
"127.0.0.1:1980": 1
}
}
}'
